-(-.h me tollo'vv Gamer-as, of ivh fication. I y My invention resides ninpro 'ticu larly or especially to elty,in'constructions adap'te. pro; vlegend or marking spacesorr the DQQM'IYOS produced. by means of suchcameras. One salient featured the invention ]S the provision. ofextremely simple means adapted to provide a; blank space on. the.

negative and adjustable as to the position of such space and as: to area0 extent.

lathe preferredembodiment of the construction, \i hich is susceptible ofemployment in cameras of all kinds, a member employed in rather closeassociation with the sensitized medium to prevent the light from actingupon a definite area thereof. so that when the plate or film isdeveloped a blank space will be provided thereon on in one desirableform oi this d4 at, he camera l around the opening through which thelight passes adjacent to the sensitised film or plate, is equipped witha groove adapted to receive a portion of the lightobstructing member,the latter being adjustable in the groove to vary the position of helegend blank and also reversible to modify the size of such blank.

In order that those skilled in this art may have a full and completeunderstanding or" this invention, 1 have illustrated an embodiment ofthe same in the accompanying drawings which form a part of thisspecfication and to which reference should be had in connection with thefollowing dc- 3 is a perspective view the forming member.

The camera may be of or form of construction. (Figs. 1 and 2), isassocia expansible and collapsiule b i l, all oi rustin 'er- J sin...)

former being only, approximately one-half.

as wide as the latter. Yl henthe flange 22 is placed in the groove 18,the part20 will rest on the inner-"face o't' theirame 10, as shown v nFigs. 1 and f2, theport1on21 projecting into the aperture of the framedirectly in a front oi' the sensitized plate 23, obscuring-a portionthereof, and preventing the light ting on such section during the usualwe of the plate after the slide 24 of live 1 has been removed. Due to 3is close to the surface o'l ll dry-plate 23, the edges of the legendblank formed will be sharp -lurreo'. flange 21 may be of a width toproduce a blank space on the negative suitable for the reception or" aone-line legend. Incase a larger blank is desired, such as willacconmiodate a two-line legend, the flange 21 is inserted in the groove18, permitting the wioer liaiiige "22 to obstruct the light missing tothe plate. It is preferable in either instance to so position the member19 that the upstanding flange will be close to the pla'e rather removedtherefrom by reason 0'. offset referred to. This is clearly illustrated-.in Fig. 3..

.Zll capability of the member ,szroore, its position may be led and themember may be any one of the four faces of :6 position for suchme1nlotted. lines in the uptron of Fig. 2.

1 have herein presented in detail a 'aiilmdinient of the invention, itis oozl that many minor mechaninay be incorporatedin the de outdeparture from. the substance of the invention and without the sacrificeof any of its substantial benefits and advan- -tages. For example, thelegend member might beadjustably positioned on the plateholder,considering the latter as a part of I the operative camera structure.

I claim:

1. In a device of the character described, the combination of a camera.having a groove adjacent to the opening through which the sensitizedmedium is exposed to the light,

and a member adapted 'to be detachably accommodated partially in anypart of said groove and project therefrom 'slightly to shield a portionof the sensitized medium near themargin only thereof to prevent exposureof such portion during the subjecting of such medium to the action oflight in taking the picture, whereby to leave a blank space on thenegative in addition to the usual unexposed marginal portion for thereception of alegend, said member, being removable from said groove by abodily sensitized medium is exposed to the light,

and a member adapted to be detachably accommodated partially in anypartotsaid groove and project therefrom slightl to shield a portion ofthe sensitized me ium near the margin only thereof to revent exposureofsuch' portion duri t 0 subjecting of such medium to the action of 1iht in taking the picture, whereby to leave a lank space on the negativein addition to the usual unexposed mar 'nal portion for the reception ofa le ncfi said member being adjustable in sai groove to vary the area ofsaid blank s ace and removable from the groove by a b ily movementthereof out of the groove and inwardly of the camera, substantially asdescribedv 3. In a device of the character described, the combination ofa photographic camera grooved adjacent to the opening through which thesensitized medium is exposed to the light, and a reversible memberhaving two olfset portions of different areas either of which is adaptedto be received in the groove while the other overlies a marginal portionof the sensitized medium to prevent exposure thereof during thesub'ecting of such medium to the action of lig t in taking the picture,whereby to leave a blank space on the negative for the reception of alegend in addition to the usual unexposed, marginal portion,substantially as described.
